Here we left Kaiser alone for 5min, that day we spent most of the time with him at home. The Kong toy was filled with treats, somewhat easy to get out. The toy goes under bookshelf right before he goes to the door.
This day we left him with food outside for a couple of hours and after getting back home, staying for 2 hours we go out using the same distraction as the day before. This time he howls. My phone couldn't record any longer but it shows he can be distracted for about 5 min. The toy was full of high value treats and it was difficult to take out.
